There is snow out there so these aren't really comparable to any others. Mind, it does make the beams look more impressive.
The more powerful of these really need a longer test range than my backyard. Maybe when the weather's better I'll get out into the sticks where there's room to play.
The participants were Fenix P3D (OK, not an 18650 light - running on a pair of RCR123s). I think this is a Cree P4 emitter. When using RCRs there is no difference between high and turbo. Doesn't get hot. Will run on a 17670 for about 40 minutes on turbo
Aurora SH-032 stainless steel. Pretty small for an 18650 light. 3 modes - high, low strobe. Does get hot - will burn your hand after 40 minutes.
Generic R2 dropin in an Ultrafire WF-502B. I have a few of these single mode dropins. They throw well but seem pretty dim indoors because of the tiny, but very bright spot. Doesn't get more than warm.
Mystery KD quad-die LED in an Ultrafire WF-504B. 5 modes in a very odd sequence. Starts in high, then strobe, the SOS, then low, then medium. Strange and not very useful.
DX 5 mode R2 dropin that came with Ultrafire WF-504B. Nice, throwy, bright. Gets warm after an hour or so. Gives 2hr on high.
DX MC-E dropin in an Ultrafire WF-503B. 3 mode - high low strobe. Gets hot, but won't burn your hands.
Uniquefire T5 - now a single mode. Gets hot, but not hand burning unless you use RCR123 in it.
Aurora AK-P7 two mode via a resistor in the switch. Same body as Ultrafire C8. One of the warmer P7s
Ultrafire WF-500 2x18650 incandescent. Bright and a tight spot
Ultrafire RC-T5 4 LED 3 modes - high low strobe
Ultrafire RC-T6 3 modes and no silly flashing ones
ROP Low (In a 6D Mag)
Here they are: apart from the ROP
From the top: Fenix P3D

Uniquefire R5 on the right bottom.
So here we go:
Control shot
Fenix P3D Low
Fenix P3D Medium
Fenix P3D High
Aurora SH-032 Low
Aurora SH-032 High. See how the spill has lit up the house at the bottom of my garden's roof. 40 or so metres away.
R2 dropin
KD quad die Low
KD quad die Medium
KD quad die High
WF-504B
oops - forgot to take these ones...
DX MC-E dropin in WF-503B. This one doesn't tailstand. Low
DX MC-E High - see how much of the roof behind the tree is lit up, and that's the spill. Approximately 40m/140 feet away I think.
Uniquefire T5. Nice body, fried dropin. Still bright.
Aurora AK-P7 low
AK-P7 High
That is bright.
Ultrafire WF-500 incandescent. This won't work with protected 18650's as it draws something like 4 amps. Note the tight hotspot
RC-T5 High (This was one of the last taken and I was getting cold so forgot to do the low shot.)
RC-T6 Low. Lots and lots of lovely flood. See how much background is illuminated - this one's more of a high powered flood than a thrower.
RC-T6 Medium. Note how this has whited out the snow completely.
RC-T6 High. Now that's a lot of light.
ROP Low, in a 6D Mag. Not entirely practical but it throws for ever. This is the tightest focus I could get with a cut down stock Mag reflector. Which will melt if you run it for too long. As will the plastic lens. I have a metal reflector and glass lens to replace those items but since it hasn't melted yet, I've not bothered.
